SSL VPN site to site

Question

Hello everyone, 
 
 I have been playing around with VPN tunnels now for a couple of weeks but everything is unsatisfying. 
 
 Current situation is IPSec site to site VPN with two Sophos XG. 
 Unfortunately the speed via VPN is not the best. 
 WAN ~ 20 - 30 Mbit 
 IPSec <= 10 Mbit 
 
 I have been playing around with MTU settings but nothing worked.

I wanted to try the SSL VPN site to site setting as I am using ordinary SSL VPN on my mobile phone to tunnel my traffic. 
 For site to site it seems that the traffic is not being tunneled. 
 
 Is there a possiblity to do that? 
 So main Sophos XG acts as the main gateway & remote Sophos tunnels all the traffic to the main one.

Try to use RED?

Hello again, 
 
 thanks it worked for me. 
 You just need to enable RED, create two interfaces and build some static IP routing.
